In 1877, Zuccato introduced the Trypograph, which used an alternative method for producing stencils. A wax-covered stencil was placed on a metal plate with a file-like surface with thousands of perforating points. When a metal stylus was used to write on the stencil, the stencil was perforated from below by the file.Trypographs were still sold at the end of the 19th century.
